Description
 Prints the subsequent text with the pica pitch (10 characters/inch).
 The character spacing is 20 dots (=203 dots/10 characters).
 If the character width is 20 dots or less, the character spacing is specified as 20 minus the character width.
 If the character width exceeds 20 dots, the character spacing is specified as the character width.
(The spacing between characters is 0 dot.)
In this case, the pitch does not exactly equal the pica pitch.
 With double-width characters, the character spacing is doubled (40 dots).
 With half-width characters, the character spacing is halved (10 dots).
 When the character spacing is changed with ESC SP, the setting is updated.
 This command is invalid when proportional pitch is selected.
 In outline fonts, the spacing between characters is 0 dot.
